Description

A battery cover assembly and split fusion sight Technical Field

[0001] The invention relates to a battery cover assembly and a split-type fusion sight. Background Art

[0002] The Chinese invention patent with patent number 202223132354.0 discloses a split-type fusion sight, which divides the sight with thermal imaging function disclosed in the invention patent application with patent application number 202210970881.4 into two parts: an aiming component and an eyepiece component. The circuit connection and signal transmission of the two parts are completed through PCB wiring technology, or the two parts are powered separately, and signal transmission is carried out through a wireless communication module, making the use and maintenance of the internal red dot sight with thermal imaging function more convenient.

[0003] The aforementioned invention patent realizes the fixed connection between the aiming assembly and the main body through the front card slot and the rear card seat on the aiming assembly connecting seat on the main body of the sight, the card block in the card slot and the vertical screw. This connection method, especially the method of connecting the lens end of the aiming assembly through the vertical screw, will inevitably require reserved screw hole space, occupying the installation space, which will squeeze the radial space of the lens assembly, affect the radial size of the lens, and is not conducive to the expansion of the aiming assembly.

[0004] Furthermore, traditional battery cover assemblies utilize a negative plate on the inside of the cover and a compression spring on the negative plate as the negative power source. This necessitates additional negative power sources for other circuit components within the entire product, inevitably increasing design and processing costs. Furthermore, the traditional battery cover and battery compartment are connected via threaded bolts, which can become loose due to vibrations caused by prolonged use.

[0029] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation methods, structural features and effects of the present invention are described in detail below with reference to the accompanying drawings and examples.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "aligned", "overlap", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; and in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0033] Figure 1 shows a battery cover assembly, including a cover plate 1, a negative conductive plate 2 arranged on the inner side of the cover plate 1, a conductive compression spring 3 fixed at both ends of the negative conductive plate 2, and also including a conductive sheet 4 fixed at the middle position of the inner side of the negative conductive plate 2 as shown in Figure 3, the conductive sheet 4 is fastened to the negative conductive plate 2 by two screws 5 arranged on the same vertical line; the two screws 5 correspond one-to-one with the upper positioning plunger spring conductive pin 29 and the lower positioning plunger spring conductive pin 30 arranged between the front compartment 27 and the rear compartment 28 of the battery compartment as shown in Figure 8, so that the conductive sheet 4 and the conductive compression spring 3 are connected to the negative pole of the battery, and the negative pole of the power supply is further connected to the shell of the split-type fusion sight through the upper positioning plunger spring conductive pin 29 and the lower positioning plunger spring conductive pin 30, so that the entire shell becomes the negative pole of the power supply. When designing the circuit, the negative pole of any circuit board can be connected to the adjacent shell, and there is no need to separately lead the negative pole line as before, which makes the circuit of the entire product, especially the design of the negative pole line, more simplified and convenient.

[0034] With the help of Figures 2, 3 and 4, it can be seen that a fastening assembly is provided at one end of the cover plate 1, which includes a screw 6 passing through the cover plate 1, a fixing seat 7 placed on the outside of the cover plate 1 and fixed to the outer end of the screw 6, a support seat 8 and a handle piece 9 arranged on the outside of the fixing seat 7; the support seat 8 is fixed to the fixing seat 7 located on the end side of one end of the cover plate 1; the bottom end of the handle piece 9 is connected to the other end of the support seat 8, that is, the end on the left hand side of the viewer shown in Figure 4, through a rotating shaft 16; a groove 10 is provided on the outer surface of the fixing seat 7 to accommodate the bottom end of the handle piece 9. In order to enhance the anti-loosening effect of the screw 6, a radially extending through hole 11 is provided on the support seat 8. The through hole 11 is provided from one side of the handle piece 9 Towards the other side, a steel ball 12, a coil spring 13, and a plug screw 14 are sequentially installed. The bottom end surface of the handle piece 9 is provided with a first spherical recess 150, as shown in FIG5 , and the outer side surface of the bottom end of the handle piece 9 is provided with a second spherical recess 151. The recessed opening of the first spherical recess 150 faces the through hole 11. When the handle piece 9 is in the folded state, i.e., placed parallel to the cover plate 1, the steel ball 12 is squeezed into the first spherical recess 150 by the coil spring 13 to limit the position of the handle piece 9. When the handle piece 9 is in the open state, i.e., with its plate surface perpendicular to the cover plate 1, the steel ball 12 is squeezed into the second spherical recess 151 by the coil spring 13 to limit the position of the handle piece 9. The limiting action of the steel ball 12, the coil spring 13, and the first and second spherical recesses 150, 151 limits the rotation of the handle piece 9 along the axis 16.

[0035] As shown in Figure 3, the inner side surface of the fixing seat 7 is circumferentially provided with a plurality of evenly arranged hemispherical protrusions 43, and the cover plate 1 is provided with spherical depressions corresponding to the hemispherical protrusions 43. With this structure, a sound is emitted when the handle plate 9 is turned, and a blocking effect is provided. This not only helps prevent the screw from loosening, but also allows the number of tightening turns to be known by the number of sounds, preventing damage to the thread caused by over-tightening of the screw. This further limits the rotation of the screw 6, preventing the screw 6 from rotating due to vibration, achieving the purpose of preventing the screw 6 from loosening, and then effectively preventing the loosening of the battery cover.

[0036] Finally, it should be noted that the screw 6 provided in this embodiment includes a threaded section that passes through the threaded hole on the cover plate 1 and reaches the inner side of the cover plate 1, and a smooth rod section (i.e., no threads, a smooth cylinder) that is placed on the outer side of the cover plate 1 and fixedly connected to the handle piece 9, thereby ensuring that the screw 6 will not fall off the cover plate 1 after withdrawing from the threaded hole 45 placed on the side of the battery compartment 15 as shown in Figure 8.

[0037] Figures 6 and 7 show a split fusion sight, including an inner red dot sight 19 provided with a reflective aiming optical system, and an aiming assembly 20 fixed to the top surface of the inner red dot sight 19 (in this embodiment, it can also be called a fusion camera assembly, and the name of the aiming assembly is retained mainly for the convenience of referring to the invention patent application No. 202210970881.4 cited in the background technology). The difference from the prior art is that the aiming assembly 20 is composed of a low-light night vision aiming assembly 21 and a thermal imaging aiming assembly 22 arranged in parallel at the front end of the shell as shown in Figure 7. The shell is composed of a component 22; the rear end of the shell is fixed to the top surface of the internal red dot sight 19 by a vertical screw 23; the bottom surfaces on both sides of the front end of the shell are respectively provided with screw holes extending obliquely outward and downward, which are threadedly connected with the oblique pull screws 24 obliquely arranged from bottom to top on both sides of the top surface of the shell of the internal red dot sight 19; as can be seen from Figure 8, the hatch of the battery compartment 15 of the internal red dot sight 19 located below the reflective aiming optical system is connected to the battery cover assembly 26 through the connecting shaft 25, that is, the cover plate 1 of the battery cover assembly is rotatably connected to the shell on the rear side of the battery compartment 15 through the connecting shaft 25.

[0038] The battery compartment 15 includes a front compartment 27 and a rear compartment 28 arranged in parallel. Two upper positioning plunger spring conductive pins 29 and a lower positioning plunger spring conductive pin 30 are stacked up and down respectively between the front compartment 27 and the rear compartment 28; the upper positioning plunger spring conductive pin 29 and the lower positioning plunger spring conductive pin 30 correspond to a screw 5 shown in Figure 3, thereby connecting to the negative pole of the battery through the conductive sheet 4 and the conductive compression spring 3, so that the aiming assembly and the shell of the internal red dot sight become the negative pole of the power supply, which greatly simplifies the design of the negative pole in the circuit board and improves the reliability of the use of the entire product.

[0039] As shown in FIG8 , the outer ends of the upper positioning plunger spring conductive pin 29 and the lower positioning plunger spring conductive pin 30 are respectively sleeved with a conductive cap 31 to increase the conductive contact area with the screw 5 and reduce the conductive resistivity to ensure the stability of the conduction.

[0040] Figure 9 shows a schematic structural diagram of the aiming assembly. The low-light-level night vision lens 32 and the low-light-level night vision chip 33 of the low-light-level night vision aiming assembly 21 are axially arranged on one side of the shell, while the thermal imaging lens 34 and the thermal imaging sensing chip 35 of the thermal imaging aiming assembly 22 are axially arranged on the other side of the shell; a data processor 36 connected to the low-light-level night vision chip 33 and the thermal imaging sensing chip 35 respectively is arranged in the shell; the data processor 36 is connected to the interface circuit board 38 arranged on the top surface of the internal red dot sight 19 through a circuit adapter board 37 arranged on the bottom surface of the shell (encapsulated in the shell through the bottom cover 42); a circuit main board 39 and a control button component 40 placed on the outside of the circuit main board 39 are arranged at the rear end of the shell; a control button assembly 41 is arranged on the top surface of the shell.

[0041] In this embodiment, the aiming assembly is fixed from an oblique downward direction by using the oblique screws 24 , which effectively avoids the radial space occupation of the aiming assembly by the vertical screw fixing method in the prior art.
